IP Multicast can efficiently provide enormous bandwidth savings by enabling sources to send a single copy of a message to multiple recipients who explicitly want to receive the information. But due to the complexity of IP multicast and its fundamental differences from unicast, there are not very many tools available for monitoring and debugging multicast networks, and only a few experts underst...

Multicast protocols are used to transfer the messages with a selected group of devices. Multicast is an effective method to maintenance group communication and decrease communicating energy. Multicasting can efficiently support a wide variety of applications. It is challenging to design a separate multicast routing protocol for sensor networks. The multicast routing protocols are fall under the...

Satellite-terrestrial (ST) networks, in which many nodes are interconnected by both satellite and terrestrial networks, can efficiently support multicast services. This is because satellite broadcasting is suitable for a large multicast group and a terrestrial network is suitable for a small multicast group. An ST network requires a multicast routing algorithm that can select the appropriate sa...

IP Multicast is a technique that can transmit one copy of data traffic to multiple receivers at one time. Because it can greatly save the network bandwidth consumption as well as many applications are inherently multicast-based, it has been a research focus since the idea was proposed. However, because of many reasons, such as management, security, inter-domain routing,etc, it has not been wide...

This article proposes a destination-driven on-demand multicast routing protocol (D-ODMRP) to improve the multicast forwarding efficiency in mobile ad hoc networks (MANETs). In D-ODMRP, the path from the multicast source to a multicast destination tends to use those paths passing through another multicast destination. If such multiple paths are available, the one leading to the least extra cost ...

We introduce the Addressable Internet Multicast (AIM) architecture, which extends the IP-multicast architecture with group-relative addressing information along multicast routing trees. AIM permits more e cient and sophisticated multicast routing options and encourages communication and cooperation between IP and higher-layer protocols. AIM enables sources to restrict the delivery of packets to...

IP multicast suffers from scalability problems for large numbers of multicast groups, since each router keeps forwarding state proportional to the number of multicast tree passing through it. In this paper, we present and evaluate aggregated multicast, an approach to reduce multicast state. In aggregated multicast, multiple groups are forced to share a single delivery tree. At the expense of so...

Key distribution is an important problem for secure group communications. Multicast is an efficient means of distributing data in terms of resources usage. All the designated receivers or members in a multicast group share a session key. Session keys shall change dynamically to ensure both forward secrecy and backward secrecy of multicast sessions. The communication and storage complexity of mu...

In this paper, we study several multicast schemes in optical burst-switched WDM networks taking into consideration of the overheads due to control packets and guard bands (GBs) of bursts on separate channels (wavelengths). A straightforward scheme is called Separate Multicasting (S-MCAST) where each source node constructs separate bursts for its multicast (per each multicast session) and unicas...
